To prevent this from happening ensure the following is set on the server:

SE Linux should be disables or set to permissive mode

Check home directory permission are set to 755 (+x needs to be set)

Umask settings should be 077

grep UMASK /etc/login.defs
# UMASK is also used by useradd(8) and newusers(8) to set the mode for new
UMASK 077

Set rp_filter kernel parameter to 2.  

sysctl -w net.ipv4.conf.all.rp_filter=2
sysctl -w net.ipv4.conf.default.rp_filter=2
sysctl -w net.ipv4.conf.ens192.rp_filter=2
